IMPROVEMENT IN ouL'TivA-roas.

Specification formingpart of Letters IatcntNo. 34,406, dated February I3; 18672# To all whom it may concern Y Be it known that I, JAMES COLLINS, of Farmington, in the county of Fulton and State lot Illinois, have-invented certain new and useful Improvements in Cnltivators; and I do hereby declare that the following is a full,clear, and exact description ot' the same, reference being had to the accompanyingdrawings, making part ot' this specification, in which- 4Figure 1 is a side elevation of the implement. Fig'. 2 is atop view ot' the same. Fig. 3 vis a rear view of the wheels, axle, plowbeams, and guide-rods, hereinafter,described. Fig. 4 is a detached view, on alarger scale, ot' the clevis, wit-h a portion of the draft-rod and brace by which each plow-beam is attached to the tongue.

Similar letters of reference indicate correspondingparts in the several figures.

My invention consists, first, in a combination of pendent rods and braces for attaching the plow-beams to the upper or main frame;

second, in a-device for permitting a'free vertical 'and lateraLmotion-of --the-plow's, and at the same timesecurin g them from rocking or departing from a correct vertical position third, in an improved device 'for moving the 'plows laterally as required; fourth, in a general combination of devices adapted to increase the eciencyof the implement and its ease of operation in cultivating growing crops.

Tc enable others skilled in the art to make and use my invention', I will lproceed to describe its constructioni and operation.

a a' representa horizontal iron bar, passing transversely through a mortise on tbe tongue b b', and secured at its ends to brace-rods c c', which extend from the underside of the axlet'ree e e forward to the tongue b b. Near the outer end sof the cross-bar a. a two pendent vertical draft-rods. ff', are attached, as shown in Fig. 1, and to the said rods ff', near theirlower end's,iron braces h h are welded. -The said braces extend from the draft-rods backward to the under side of the'axle-tree in aline 'with the plow-beams i i', and are suiciently i strong to sustain tbe draft ot' the plows. By

this means thependent rods f j' may project horizontal position, and still dispense with-the vnecessity for'oblque draft rods or chains extending in front of the wheelsand beneath the' tongue.. The efficient andeasyoperation of `the machine is thus .greatly promoted.

g represents a hinged clevis, attached to the front end of each of the plow-beams t' i in the following manner: An iron plate of sufticient length is securely bolted on each side of the beams, projecting in frontthereof suficiently:

farto'receive the end ot' the clevis, which is inserted between them and secured by a niccly-fittingbolt, l'orminga hinge-joint, which per- Fig. 1 and formed with eyes, which 't upon the lower ends of the rods ff below the braces h h, the sai-d lower ends ofthe rodsbeing made y round for this purpose. By this inode ot'attach mentfree vertical and lateral motion is afforded to the plows, while they are at'the same time eiectually secured against rocking or any deviation from acorrect vertical position.

lc le' are Vertical crank-levers, which ina-y be attached either to the front or backot' the axls e e. The wrists ot' the said levers may be journaled to the axle in any suitable manner, and the lower ends are received and work loosely in mortises in the beams, the said mortises being about three inches long and suffi-- ciently wide to allow the beams to work freely up and down. The arms ot' the cranks maybe about rsix inches in length, and one'of the rods extends backward, as shown in Fig. l, a s'ucient distance to enable the operator by ap plyingy a hand thereto .to move the plowslaterally in either direction while at work.

l l isla tie-rod connecting the crank-levers together, so that-a simultaneous mo\ ementmay be imparted to both plow-beams. The crank-v levers above describedare threaded for a short distance at their,lowerends,an d a .nut,, is applied thereto for the purpose of adjusting th'e height ot' thefbeams and thereby the depth at which the` plows will work. Similar threads and nuts upon the rods ff( permit the adjustv ment of the forwardends'of the beams, so that while set at any height desired the beams may be retained in a horizontal position.
